Similar letters and figures of reference denote corresponding partsthroughout the several views of the drawings.

My invention relates to that class of caloritics or heating devicesdenominated ranges,

and which as is obvious includes under such designation stoves andanalogous devices particularly adapted for cooking and baking purposes.

The object of my invention is the production of a device appertaining tothe class described, of improved and advantageous construction andoperation; non-complex and inexpensive of manufacture as compared withthe common forms of ranges and stoves; of exceeding utility combinedwith great econcmy in utilization of space of the component partsentering into the formation of the complete range; that is susceptibleof disposition in any desired portion of a room; that will boil, bake,steam, 85G. satisfactorily and with exceeding dispatch; that utilizes inlieu of coal or wood for fuel, refined petroleum,gas, or other liquid orgaseous products for the production of requisite heating powers at avirtually nominal expense and, in novel details of construction andcombination thereof imparting great efiiciency and satisfactory workingto a cooking range of the species designated.

My invention consists in the novel features of construction, combinationof co-operative parts, and operation and adaptability as hereinafterfully described, and specifically set forth in the annexed claims. It isconstructed as follows:

a, indicates the exterior casing of the main body portion A of mycooking-range, which casing, rectangular in form, closes the top,bottom, sides and ends of the aforesaid body except at such points wherethe casing is perforated or cut away in the manner and for the purposeslater to be set forth; said casing creating the interior portion of therange that is subdivided into chambers and flue portions later to bedescribed.

1- denotes the supporting framework for the range body, comprisingvertical legs or standards 1 disposed at the four corners of the body,boundary side and end rails 1 connected with the upper termination ofthe legs,

and upon which rectangular railing the body 1 A. is suitably mounted,andv tie-bars 1 ex-: J

tending from. leg to leg, one of which serves as a support for a lamp oranalogous heatgenerating medium, as later particularly referred to. B isthe rectangular oven or baking cham ber of my device, situatedlongitudinally central within the space inclosed by the casing a of therange body, and perpendicularly located much nearer the top of the rangethan the bottom; and O a hot-air flue chamber or jacket space surroundin g the aforesaid oven at its bottom, ends and top, and createdconjointly by the rectangular non-perforated casing b forming the ovenchamber and the end walls and bottom plate comprising the casing 0located a brief distance from the oven walls afore mentioned inconnection with the topplate of the external casing a, situated a briefdistance from the top of the oven.

2 is a circular stove-hole in the top-plate of the range directly overthe oven, and which is invariably retained unobstructed by anystove-griddle or lid, and circnmferentially surrounding said centralstove hole are lugs d, adapted for the support over the same of akettle, spider or other culinary appliance to secure all requisite heatand yet form no obstruction to the egress of the heat or products ofcombustion escaping through it; and 3 is an elongated slotted openingformed in the bottom plate of the casing 0, directly underneath theoven, and extending from the front ofthe range body rearwardly to apoint approximating the back of the overhead oven.

D denotes a combined hot-water and steamgenerative tank, the mainupright portion fwhereof is rectangular and of a size when erected inits place in the range body, and seated upon blocks 6 located on thebottom plate of the exterior casing a, to extend vertically from Withina brief distance of the bottom plate aforesaid to within a briefdistance of the top-plate of the external casing, whilelongitndinallyextending the length of the stove and, the back wall of the casing abeingtcut away throughout its length and throughout its height exceptadjacent the top and" bottom of the range body, an opening 4: ofrequired size is allowed whereby the tank D, is readily insertible intoits seat within the casing a of the range, slipping in to place'betweenthe end walls of the external casing and occupying by its uprightportion f aspace transversely about one-third the width of therectangular body A, its front wallstanding against the rear wall of theoven-chamber B and endwise projecting portions ofsaid back wall of theeven, while those portions-of the front wall of the upright part of thetank afore mentioned that project lon gitudinally beyond either end ofthe ovenchamb'er serve as back walls to the lamp or combustion-chamberslocated at each end of the range body. Forwardly and centrally thevertical portionfof the tank D terminates with a flattened horizontallylying hollow portion f communicating throughout its interior diameterWith the hollow upright partf, which laterally horizontal projectingportion f is water and steam-tight as is the vertical part f, and firmlyconnected with the vertical part aforesaid by riveting, soldering orother satisfactorymanner. The vertical portion f of the tank Disperforated and provided with tubular connections at certain points asand for the purposehereinafter mentioned. The flattenedrectangular-shaped hollow extension f of the tank D lies, when the tankis mounted in po sitionin the range body underneath the bottom of theoven B at a medium distance therefrom, extending from its junction withthe uprightportion f contiguous the back termination of the ovenforwardly the ovens width, and in wid th occupying an area coinciding tothe length longitudinally of the oven chamber. The even B extends fromits point wall of brief distance outwardly from the end walls of thecasings (as well as end walls of the projecting portion f of the tankD), which partitions extend from the front wall of casing a rearwardlyto the forward wall of the upright portion of the water and steam tank,and extending vertically from the bottom of the range body upward to apoint horizontally lineal with the top of the said tank and the oven,creating above the top termination of the partitions g, g elongatedopenings 5 located between the open tops and the overlying top-plate ofthe range. The rear wall forming the back of the oven chamber B extendssuch distance beyond either end thereof as '.to form a back wall to theflue chamber 0, and to the fine chamber E; which last named chamber 'isconjointly created, by the partitions g, g, adjacent 'interiorly'located end-walls of the casing c, the top, bottomand end walls of thehorizontally projectingvportion f of the tank D, and the bottom plate ofthe external casing of the body ofthe range, the portion f of theaforestated tank lying practically midway between thebottom plate of thechamb the casing a, and centrally a brief-(distance from the partitionsg, g, whereby an unobstructed passage is afforded entirely around theoutside of said partfof the tankas well as that afforded between thepartitions g,,g and the adjacent inner lying end walls of the casingcofthe flue chamber C. The front portion of the casing a is cut away at butone point, and that Where it. faces the oven chamber, which opening F isof corresponding diameter to the oven and provided with a double-casedhollow door G, suitably hinged at a side and having a knob or othersuitable grasping orlockin g device.

the tops of the partitions g, g. The lamp chimneys at their bottom partare provided atthat side adjacent the ends of the range body with asuitably sized opening closed by a door Z, properly hinged and securedinv place,whereby when wished the lamp body and its burner may rcadilyberemoved from position in the lamp or combustion chamher, withoutdisturbance of its overhead secured chimney portion, by merely openingthe hinged door Z, thereby facilitating the con joint removal of thelamp and its otherwise non-laterally movable burner portion.

K, K denote the oil supply reservoirs for the aforesaid lamps, which aresituated slightly back of the lamp bodies and their interiorscommunicating with the usual reservoirs of the lamp bodies by means oftightly connected feed-ducts 2'; andj are filling tubes for the oilsupply reservoirs, provided with a screw-cap, or analogous device. Theoil-supply reservoirs K, are mounted similarly to the lamps L, uponbridgedike supporting bars tion or withdrawal of the lamps L into or outof the lamp chambers is attained by means of the permanent large squareopenings 7, 7, existing in the respective end-walls of the externalcasing to, of the range body, providing ample room for the insertion orremoval of the lamps and connected adjacent reservoirs, and concurrentlydesigned to permitof abundaut entrance of cold air, into the lampchamhers insuring coolness thereof and thus obvi- 'ating liability ofundue heating of the lamp reservoirs; besides creating a splendid draftand insuring good and satisfactory combustion of the oil when the lampsare burning. The end walls of the casing 0 continue rearwardly throughintegral strip-like extensions over the verticalportio'n f of the tank Dthereby oompletely separating vertically from front to back of the rangebody the flue-chamber G. from the outer lying liue portions, saidoverhead extensions being indicated by the letter 75. and 7t, 7t, denotelongitudinal partitions projecting from the top plate ofthe range, inline with the front wall of the vertical division f of the tank D, saidpendent partitions extending, at the localities indicated, from therespective end walls of the casing c. to the contiguous range ends, andthereby fully separating thereat the fore lying portions of the rangefrom the adjacent chamber portions located directly over the verticallystanding partf of the tank 1)..

L indicates an oil lamp (or other heat producing appliance) of largecapacity, located directly beneath the circular opening 8 in thebottom-plate of the casing a, and directly beneaththe. fiat contractedextension portion f of thetank D,thelamp bodybein g supported at itsiutegral reservoir portion bybein g mounted on a tie-bar 1 of thesupporting framework of the range body, as illustrated. The aforesaidlamp, having usual burner, &c., is provided with a chimney M fastened tothe overhead bottom of the range, and fitting the periphery of theopening 8, said chimney at'its lower portion being provided with anopening at its front side closed by a door 1', permitting when opened ofthe lateral insertion or withdrawal of the burner portion of the lampconcurrently with coincidental manipulating of the lamp body. Obviouslysaid door is provided with a suitable latch to insure the doors suitablefastening when closed.

9, 9, are stove holes in the top plate of the range body adjacent to theends thereof, and located diametrically over the end lamps L, L, aforereferred to, which holes are normally retained closed by means of lidsor griddles 10, 10, although when advantageous to one or both'thegriddles may be removed-but occasion for such procedure will rarely, atthe utmost arise, except when a kettle, frying pan or other cookingutensil is to be disposed over the open stove holes, in which case, asis evident, the closing of the holes by a culinary appliance insures theclosing thereof in the same degree that the stove lids otherwise attain.

11 denotes a supply or filling tube projecting from an end of thecombination hot water and steam tank D, and projecting thereat adjacentthe top part of the standard portion f thereof, which tube communicatingwith interior of tank is used for filling the tank about two thirds fullof water; which tube is provided with a screw-cap or other suitablestopper.

12 is a faucet located at an end of the aforementioned tank adjacent thebottom of its upright portion, and whereby hot water for culinary orother purposes may readily be obtained from said tank. Obviously the endportion of the external casing a is slotted from the-rear portion suchdistance as to admit of the passage of the aforementioned supply tubeand faucet into place when the tank is slid into position in the rangebody, as indicated to some extent at 0, Fig. 5 of the drawings.

N indicates a warming-oven located over the rear portion of thetop-plate of the range body at a suitable distance therefrom, andsupported in position by means of large-sized 'vertical pipes O, O,erected adjacent to the opposite end portions of the top of the rangebody, and which respectively communicate with the interior of the mainrange body and the interior of the warming-oven, and whereby hot-airpasses upward into the aforesaid oven. Said warming-oven comprises alarge central chamber 13, and a surrounding flue compartment 14, createdby a rectangular inner casing a, disposed at all points a brief distancefrom the external casing 0, of the said oven. The hot-air pipes Ncommunicate at their lower ends with the hot-air compartment portionexisting beneath the range-top and rearward of the side lamps, and attheir upper ends with the central receptacle chamber of thewarming-oven.

Q is a steam-supply pipe leading vertically from the top portion of thesteam and hotwater tank D. upwardinto the steam compartment let of theWarming oven, and provided with a steam regulating valve 19 forregulating the flow of steam into said compartment. If so desired, theupper end of the steam pipe Q may be so constructed as to enter thecentral chamber of the oven as indicated by dotted work 1*, Fig. 6 ofthe drawings, whereby said central chamber 13 is thereby converted intoa steamer or steaming oven in lieu of an ordinary warming oven heated byexteriorly circulating hot air. By my primary form of arrangement thehot air pipes retain the central chamber of the warming oven warm by thedry hot air entering therein, while the steam entering the steamcompartment through the steam supply pipe, and circulating around theexterior surface of the central chamber serves as an auxiliary heatingmedium besides retaining requisitely moist the contents of the centralwarmingchamber.

P is a steam escape-pipe located at the top of the warming oven adjacentthat corner thereof diagonally opposite where the steam enters, whichescape pipe leading from the steam compartment is utilized forpermitting the exit of any undesirable amount of steam in thewarming-oven, said steam escape having a screw-cap to stop or permit ofthe escaping of the steam, through a suitable perforation at the topportion of the said pipe. The warming chamber of the warming-oven N hasan opening or openings at its front provided with one or two doors Rsuitably hinged and provided with ordinary fastening devices, wherebyarticles of food may be, when doors are opened expeditiously depositedwithin or removed from the warming chamber.

S is an automatic steam-drying cylinder appertaining to my improvedconstruction of cooking range, suitably supported adjacent to the mainrange body, which cylinder (represented in the drawings as standingvertical is closed at its otherwise open top by a flanged head 15detachably secured in place, and at its conical bottom portion with avalved outlet pipe m, leading therefrom, the cylindrical portion of thecylinders interior having a fine sieve or meshed wire fabric 8 arrangedcentrally vertical therein and extending from the top to the bottom ofthe chamber, and extending across from side to side of the circularinterior, while at a point a distance beneath the top, and at a point adistance above the bottom of the chamber are circular fine sieves ormeshed wire fabric S S respectively, of the diameter of the chamber,suitably held in place; the vertical transverse sieve intersecting theillustrated.

T is a steam-supply pipe leading to an end of the body of the range, bysuitable connection from the upper portion of the interior of the steamand hot-water tank D, and provided with a regulating valve 16 adjacentthe range body, which pipe by a bend vertically down ward enters throughthe head of the steanrdrying cylinder S and passes through the firstcross-sieve 8 down nearly to the lower cross-sieve s whenceitterminates, said pendent pipe portion being located to one side of thevertical sieve 8.

At the opposite side of the cylinder S is a steam feed-pipe u providedoutwardly with a T-coupling n; and inwardly, by a bend excircularcross-sieves as tending vertically downward through the cylinder-headinto the chamber of the steam drying cylinder at that side of thevertical sieve s opposite to that where the first-named pipe isstationed which pipe t6 projects only a brief distance down, terminatingcontiguous the top face of the first cross-sieve 8'.

At that end of the range body where the steam pipe leading from the tankD to the cylinder S enters the casing a, a slot extendingtherefrom'rearward to back of the range body is formed as indicated at25, whereby no barrier is presented to the admission thereof incidentalto the sliding of the tank D into operative position within the casinga.

My purpose in having the steam supply pipe leading from the tank Dthrough the end of the external casing of the range body outward, is tofurnish requisite steam heat, to any auxiliary attachments such assteaming appliances or other devices which it may in practice appearadvantageous in certain instances to make use of, and the object of thesteam drying cylinder S forming a component part of my invention, is toinsure as thoroughly dry steam as possible for Whatever auxiliaryappliances the steam may enter. The function of the said sieve-providedcylinder in conjunction with the inlet and outlet steam feed pipesextending therein,being to automatically dry the entering and passin gsteam through the separation of the water from the steam, the meshes ofthe fine sieves intercepting and collecting the water of condensationand practically dry steam being resultant. Obviously in the passage ofthe steam through the perforated barriers adherence of a large amount ofexcess moisture to the meshes must evidently occur.

For the removal of the water of condensation accumulating in the bottomportion of cylinder the valved discharge at its conical termination isemployed.

\Vhenever so preferred the steam drying cylinder may be disposed on aslightly upward incline from a horizontal plane, in which case its waterdischarge-pipe would be arranged to communicate with the tank D at suchlocation that the water of condensation and mingle with the water.therein.

would, through gravitation, flow into the tank Obviously, variations inthe incline or location of the cylinder 8 may be made without effectmgthe material construction of such portion, the position and locationbeing governed by preferences or circumstances.

lhe operation, briefly stated, of the main body portion embodied in myimproved construction of cooking range, is as follows: The heatgenerated by the central lower lamp or other suitable heat-generatingappliance) passes upward through the opening in the bottom of theexternal casing, underneath, around, and over the horizontal low-l yingpro- 3ecting portion of the combined hot water and steam tank, heatingthe contents, and thence upward through the overhead. central openinginto and up through the flue chamber directly inclosing the oven,circulating around outside said even and passing over it escapingthrough the central normally open stove hole in the top plate of therange directly -indirect radiation fully attained.

over the oven chamber;- while concurrently the heat from the upper lampsarranged at the opposite extremities of the range body, passes throughthe centrally facing openings in the lamp chimneys then through theelongated openings existing above the top termination of the contiguousflue chamber walls, and downward the interior of said chamber to andover the underneath located extended portion of the steam and watertank, whence the heat passes upward through the overhead opening intothe flue-chamber inclosing the oven, and thence upward around the casingof the oven and through the central opening in top of the range body,the cummingling of the heat or products of combustion arising from theburning central and end lamps insuring thorough heating of the oven andthe subjacent tank, and all direct and By the indirect radiation of heatfrom the fine chambers and the oven whencontiguous to the front wall ofthe hot water and steam tank, said tank is at its vertically standingpart thoroughly heated. Moreover the direct heat passes over the top ofthe said upright portion of the tank at its middle portion, and to somedegree underneath the same.

Whenever deemed advisable or advantageous to so do, I slightly modify orvary the construction of the main body portion of my range, bydispensing with the casing directly inclosing the casing forming theoven, coincidently continuing the side walls of the oven upwardly to thetop-plate of the range body and-terminating said. extensions rearwardlylineal with the front face of the combined hot-water and steam tank,while conjointly circular openings (as indicated by dotted lines 17, 18,Fig. l), are formed in the top and bottom of the oven casing.

In my aforedescribed in odiiied form of construction, the heat from thelower central lamp passes up through the opening in the bottom of theexternal casing, under around and over the projecting horizontal portionof the hot-water and steam tank, and thencedirectly upward through theoven chamber, (instead of circulating around), and passing out throughcentral overhead opening in the topplate of the range body. Concurrentlythe heat from the end lamps passes inward striking the outer surface ofthe end walls of the oven casing, and passing downward and under theoven commingles with the hot air arising from the lower central lamp,and entering the lower opening in the oven casing, circulates upwardthrough the oven and passing through its top opening is dischargedthrough the central overhead stove holein the top plate of the rangebody.

The manifold advantages of my improved construction of a cooking rangefor baking, cooking and steaming purposes, &C., by rea son of its noveland thoroughly operative formation is readily apparent.

Obviously, if so wished, the construction of my range may be so modifiedthat the large body portion f of the tank D shall occupy in the rangebody that portion occupied by the oven in my primary construction, whilethe flattened projecting portion f of the tank will project horizontallyrearwardlya reversal of position of the tank, and the oven thereby lyingat the back portion of the range body and having openings and doors ateither end for access thereto.
